  • Cement manufacturing process: Stepbystep guide

    720 Step 1: Mining The first step of Cement manufacturing process is to quarry the principal raw materials, mainly limestone, clay, and other materials. Step 2: Crushing After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.Cement Production Process Cement Manufacturing ,825 There are three steps of the hightemperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.11.6 Portland Cement Manufacturing US EPA,1971817 11.6 Portland Cement Manufacturing 11.6.1 Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of The initial production step in portland cement manufacturing is raw materials acquisition. Calcium, the element of highest concentration in portland cement, is obtained from a variety of
